Hi,

I have a switching pc power supply off a 4 year old PC presently configured
for 220 V AC input and I would like to alter it to run on 110V input.  The
label says that it is a dual input type and that it may be switched
accordingly.  However, there is no such switch and I'm wondering whether two
free terminals on the PCB with a rectangle drawn around them (labelled
110V - 220V) represent the location where two switch leads are intended to
be soldered in place and when the switch is thrown to closed circuit thereby
joining these two terminals - whether that is a voltage halver (it seems to
connect to some resisters that might have that effect).  If so, then I plan
to solder in a bridge.


Any ideas?
Thanks - Rich
